DETAILED DESCRIPTION OF THE EMBODFIMENTS

[0017] In order to make the technical problem to be solved by the present disclosure, the technical scheme, and the beneficial effect to be more clearly understood, the present disclosure is further elaborated together with the drawings and embodiments. It should be understood that the specific embodiments described here are used only to explain the present disclosure and are not intended to limit the present disclosure.

[0018] A luminous protective case for an electronic device, as shown in FIGS. 1-5, includes a casing 1 that matches the dimensions of the electronic device, an electronic circuit board 3 provided along an inner side of a grooved frame of the casing, a magnetic adapter 2 provided on the electronic circuit board and insertable into a preset interface of the electronic device, a plurality of light-emitting sources 4 distributed in and along the grooved frame of the casing, and a main control circuit that controls the light-emitting sources. A magnetic end 21 of the magnetic adapter is exposed from the casing.

[0019] Among them, the electronic device may include, but is not limited to, a smart terminal such as a smartphone, tablet, etc. The magnetic end of the magnetic adapter can be used for the charging of the electronic device, and the other end can be used to insert into a preset interface of the electronic device, such as USB, lightning interface, etc.

[0020] The light-emitting sources are distributed along a periphery of the casing and can produce a side lighting effect. Specifically, the light-emitting source can be a light-emitting diode (LED) light or an electroluminescent (EL) light source.

[0021] The electronic circuit board may adopt a narrow printed circuit board (PCB) for space saving and setting along the side frame of the casing.

[0022] Further, a wireless coil and a rechargeable battery may be respectively connected with the main control circuit, so that the protective case can be used to wirelessly charge an electronic product or charge as a back clip rechargeable battery, thus meeting more requirements of a user.

[0023] Further, in an embodiment, the electronic circuit board may be divided into a first printed circuit board 31 and a second printed circuit board 32 for easy installation, wherein the first printed circuit board is provided with the main control circuit and the magnetic adapter, and the second printed circuit board is provided with the light-emitting sources. Preferably, the second printed circuit board adopts two strips of flexible printed circuit (FPC) board respectfully distributed along an inner periphery of the casing. A flexible printed circuit board is lighter in weight and lower in cost.
